Since those lines are parallel, those two angles are equal. Therefore:
3x+15=105
3x=90
x=30
Answer:

Step-by-step explanation:
<u>Volume Of A Pyramid
</u>
The volume of a pyramid is computed as one third of the product of the area of the base (B) by the height (H):

<em>The question doesn't ask for anything in particular, so I'm computing the volume of the solid shown in the image
</em>
We have a rectangular base of dimensions 15m x 60 m. The area of the base is

We now calculate the volume, knowing the height is 55 m


for this problem the answer is 9x-3
Answer:
exact volume= 12320ft³
approximate volume= 12308.8ft³
Step-by-step explanation:
exact volume= 22/7×14² x 20
approximate volume = 3.14x14²x20
Answer: second option Let (2a +1) be an odd number. Let (2b +1) be a different odd number. Because the sum of these two numbers, 2(a + b + 1), is a multiple of 2, it is an even number.
